The properties of the new resonance observed at the LHC in 2012 [1]}, [2]}
seem tantalizingly close to those of the Higgs boson predicted by the
Standard Model (SM) (for instance, see [3]}, [4]}).
The particle spectrum predicted by the SM has now been fully confirmed, but
many important questions in particle physics are left unanswered: the smallness of neutrino
masses, the fermion mass hierarchy, the colossal asymmetry between the quantity of
matter and antimatter in the universe and the nature of dark matter are a few of such unresolved issues. They are usually taken as hints for the existence of new physics (NP) beyond the SM (BSM). Typical BSM scenarios
that aim to fix one or more such shortcomings of the SM often end up
extending the scalar sector of the SM. In these extensions, the 125
GeV scalar observed at the LHC is not the only scalar in the spectrum
but the first one in a series of others to follow. This is an
intriguing possibility which motivates us for a closer inspection of
the properties of the observed scalar and inspires us to carry on our
efforts to look for new resonances at collider experiments.
